Problem
The mining industry faces challenges in recovering valuable metals from complex polymetallic ores and mine tailings, leading to significant resource wastage and environmental liabilities due to acid-generating potential and ecological threats. Traditional methods often involve high energy consumption, specialized equipment, and generate further waste, making many projects uneconomical and environmentally unsustainable.
Solution
EnviroGold Global provides a hydrometallurgical technology, the NVRO Process, that enables mining companies to monetize previously unrecoverable metals from mine waste and tailings. The technology employs a weak acid leach process at atmospheric pressure and relatively low temperature, using an exothermic reaction with a short residency time. This process frees metals trapped in pyritic and volcanogenic massive sulfide ores (VMS) and neutralizes the acid-forming potential of waste material, reducing environmental concerns. EnviroGold Global partners with asset owners to deploy this technology, optimized for site-specific geologies, and can finance and install modular, scalable plants for commercial production.
Target Audience
The primary target audience includes mining companies seeking to improve resource recovery from complex ores and remediate mine tailings, as well as governments and industries aiming to address environmental and ecological threats associated with mining operations.
